Modify/download part (OnShape, requires account): โ€œTo build the valve you will need some sort of thread sealant, I use teflon tape; a 35mm ++ M3 Hex Screw with two nuts, a half or third of a bic pen spring, and some sort of gasket material, like a bicycle inner tube, some shopping bags, or best, some sort of squishy silicone sheet.โ€

๐Ÿ”—https://metro.co.uk/2020/03/16/firm-refuses-give-blueprint-coronavirus-equipment-save-lives-12403815/

Venturi valve - In Italy, a replacement valve was modeled and printed using 3D Printers for roughly $1 a valve. This was done to save lives. The technologist who designed the 3D file wasย threatened with a lawsuitย by the manufacturer that normally makes the valves, and thus has refused to share the valve designs with others,ย despite the desperate need for the valves at other hospitals. More of these valves may be needed outside of Italy, and already are at hospitals outside of Brescia.
